I have a 2003 Banshee. I bought it in 2006 with low hours, never rebuilt. To put it in perspective i have all original tires, original grips(hardly worn), and little wear on frame from from my legs. in the past couple year i hardly rode it. I went to start it in the spring and no luck. I rebuilt the carbs, put fresh gas in it and still nothing. I can get it to start on eather(which I hate doing). Then when i gas it, it will make like a noise like a loud gush of air out the right side exhaust pipe. The left side smokes alot. It will bog alittle when hitting the gas then once it sees full throttle it runs like a raped date. Even driving at full throttle it feels good. But once I shut it off it wont start again without eather. So i cleaned out the carbs again and its still doing the same thing. Today i did a compression check and bother cylinders are at 100psi. Is this normal? Should i buy a carb rebuild kit? what should i check, what is your advice? thanks in advance.
